Carnegie Supernova Project: Fast-Declining Type Ia Supernovae as Cosmological Distance Indicators

M. M. Phillips, Syed A. Uddin, Christopher R. Burns +16

In this paper, the suitability of fast-declining Type Ia supernovae (SNe Ia) as cosmological standard candles is examined utilizing a Hubble Flow sample of 43 of these objects obse…

1991T-like Supernovae

M. M. Phillips, C. Ashall, Peter J. Brown +23

Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In t…

Carnegie Supernova Project-I and -II: Measurements of using Cepheid, TRGB, and SBF Distance Calibration to Type Ia Supernovae

Syed A. Uddin, Christopher R. Burns, Mark M. Phillips +44

We present an analysis of Type Ia Supernovae (SNe~Ia) from both the Carnegie Supernova Project~I (CSP-I) and II (CSP-II), and extend the Hubble diagram from the optical to the near…

The Absolute Magnitudes of 1991T-like Supernovae

M. M. Phillips, C. Ashall, Christopher R. Burns +20

1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H &…

ASASSN-15hy: an under-luminous, red 03fg-like type Ia supernova

J. Lu, C. Ashall, E. Y. Hsiao +33

We present photometric and spectroscopic observations of the 03fg-like type Ia supernova (SN Ia) ASASSN-15hy from the ultraviolet (UV) to the near-infrared (NIR). ASASSN-15hy share…
